摘要：Based on X-ray diffraction results, the gallery height of modified Mg3Al-LDH was expanded to 9.6 angstrom from the original 4.8 angstrom, indicating that the H3PW12O40 was indeed inserted into the hydroxide layers. Moreover, the results of FT-TR spectra proved the Keggin structure of PW11O397- species. The resulting material showed a high activity of degradation of methyl orange in the presence of H2O2 and UV light irradiation.
